Remove compodoc + pdfmake

As discussed in the JS team meeting on 9/23/24, figure out how to remove compodoc. We also need to remove pdfmake which was added in googleapis/gax-nodejs#1658

Per @sofisl's suggestion We can likely switch to jsdoc like : https://github.com/googleapis/google-cloud-node/blob/main/packages/google-analytics-admin/package.json#L35

Done!
